13 Claims.

This invention relates to new and useful improvements in heat savingshields for windows.

The invention contemplates a new heat saving shield for a window,characterized by a stiff board such as cardboard, or other pasteboard,and other materials, adapted to extend across the inside dimensions of awindow frame and formed with a back panel and flexibly connected sidepanels obliquely extending forward against the sides of a window frameand associated with a stiff strip adapted to be mounted'across thewindow frame and to bear against the back panel for holding the board inposition."

The new shield" for windows is particularly intended to reduce theradiation of heat through the window and window panes, as a waremergency measure to save heat. Of course the new shields are opaque andmay be used for blackouts.

Still further the invention proposes providing the edges of the stiffboard with binding material which will assist in preventing or reducingthe circulation of air around the shield.

The invention proposes various modified forms of shields, each of whichembodies the essential features of this invention. In one form certainfastening elements are proposed for'assisting in and of the objects andadvantages thereof, referv ence will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

taken on the Fig 18is a similar view to Fig. 5, illustrating anotherform of the invention.

In the form of the invention illustrated in Figs. 1-5 inclusive, theheat saving shield includes a stiff board I! for extending across theinside dimensions of a window frame such as indicated by'referencenumeral Hi. This stiff board I! has a back panel I4 and flexiblyconnected side panels In the accompanying drawings forming a matebindingand the edge of the stiff board.

Fig. 4 isan elevational view of the air shield in a collapsed condition.

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 4.

.This strip i6 may be constructed from a thin strip of wood. Fasteningelements are provided for holding the strip it as desired. As disclosed,this fastening means includes a fastening element- I! connected betweenthe center of the strip l6 and the center ofthe board. Thus, the stripI6 is not only connected with and supported on. the board II, but itmaypivot to a vertical position, as for example shown in Figs. 4 and 5.However, the strip l6 may also .be sold unattached.

The window frame I3 is provided with pins I! or other abutment behindwhich the ends of the strip iii are engaged. Thus, the strip l6squeezing against the back panel l4 holds the board in position. Theresiliency of the connection between tre panels l4 and I is dependedupon to cooperate with the strip IE to hold the board. Another pin I 9is driven into the base portion of the window frame l3 and engagesagainst the bottom of the board l2, assisting in holding it in position.

Binding strips are attached to the edges of the board i2. Prefe ably,these binding strips are of cloth or'o'ther soft material. They areattached by 'lmes of stitches 2|, or in any other way. They engageagainst the window frame l3 and serve to reduce the circulation of heatand air through the window. When the air shield is not in use it may befolded as illustrated in Figs. 4 and 5 and stored away.

In Figs. 6 and '7 a modified form of the invention has been disclosedwhich is similar to the prior form, distinguishing merely in the way inwhich the stiff strip I6 is supported. In this form of the invention oneend of the'stiff strip I6 is pivotally connected by a pintle 22' with afastening element 23 mounted on the side of the window frame. The otherend of the strip I6 engages behind a pin 24. Another pin is mounted onand projects from the strip 5 and rests upon and is supported by the pin24. With this construction the strip It may be pivoted to an' openposition about the pivot 22.

In Figs. 8and 9 another modified form of the invention has beendisclosed which is very similar to the first form, distinguishing merelyin the fact that the stiff board I2 is constructed with a the inventionis disclosed which primarily distinguishes from the prior form in thefact that the air shield includes a stiff board l2 formed from twosections. There is a top section 28 and a bottom section 29. Thesesections are releasibly connected with each other by a staple 3 0engaged through the overlapping adjacent edge portions. The top section'28 is supported in position by a strip l6 engaging against its backpanel. This strip I6 is pivotally connected by av pintle 22 with a pin23 mountedon the window frame. The strip l6 has another pin' 25 restingon a pin 24 on the other side of the window frame. The bottom section 29is illustrated supported in position by a stiff strip I6 which ispivotally mounted at its center by a pintle l8 upon the back panel 'ofthe section; The ends of the strip l6 engagefbehind pins I! mounted onthe sides of the window frame. In other respects this form of theinvention is similartothe previous form.

In Fig. 12 the board i2" is divided into two equal sides I5 by thevertical central crease. In other respects this form of the invention issimilar to the previous forms.

In Fig. 13 part of the binding strip 20 is stitched within the edge ofthe panel I5. In Fig, 14 the binding strip-20 is stitched at 2| to theside'of themember l5.

In Figs. 15 and,16 the panel It is illustrated with a folded edge l5andthe binding strip 20 is shown to be fastened tothe side of the panell5 by stitchesll. .In Fig. 17 the panel 15 is shown with afdouble fold I5 and the binding strip 20 is shown to be stitched at 2| to theside ofthe panel I5". 7

In Fig. 18 both side panels I5 are shown to be folded'on one side of theback panel 14.

It is to be understood that this heat saving shield may be of any shape,size and material and that the retaining strip I6 may hold the heatsaving shield in position without any holding pin, or by a stringstretched between the sides of the window frame.

While I have illustrated and described the preferred embodiments of myinvention, it is to 1 be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.
